<question id="indefinite-wait-buffer">
<para>What does the error <errorname>swap_pager: indefinite
wait buffer:</errorname> mean?</para>
</question>
<answer>
<para>This means that a process is trying to page memory to
disk, and the page attempt has hung trying to access the
disk for more than 20 seconds. It might be caused by bad
blocks on the disk drive, disk wiring, cables, or any
other disk I/O-related hardware. If the drive itself is
actually bad, you will also see disk errors in
<filename>/var/log/messages</filename> and in the output
of <command>dmesg</command>. Otherwise, check your cables
and connections.</para>
